What Is It?

Formal planters

Storage areas

Paving materials (also known as “impervious surface”) include:

What Permits Do You Need?

A grading permit is required if you add or replace 2,000 square feet (100 feet by 20 feet)or more of existing paving. If you resurface existing paving you do not need a grading permit. If you remove existing paving and replace it, a grading permit is required once you reach the 2,000 square feet limit.
